Isolated Outputs

Each of isolated output channels comes equipped with a Darlington tran-

sistor. Every 16 output channels share common collectors and integral

suppression diodes for inductive loads.

Note: If an external voltage (5 ~ 40 V

put channel while it is being used as an output channel, the current will

flow from the external voltage source to the card. Please take care that

the current through each IDO pin not exceed 200 mA.

Figure 3-3 shows how to connect an external output load to the card's iso-

lated outputs.
